TO ALL WHOM I'I MAY CONCERN:

Be it known that I, BENJAMIN F. MILLER, of the city and -State of New York, have invented and made a new and useful Improvement in Pavements for Streets; and I do hereby declare the following to be a full, clear,

and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, whereiu-A i Figure 1 is a side view of blocks, as laid longitudinally of the street.

Figure 2 is a plan of the same. V

Figure 3 isa side view' of a range of blocks, with their longest measurement in the opposite direction to those; and

Figure 4 is aplan of the same. v

Figure 5 is a side view of thin blocks or pieces of plank, the required length, with their ends sawed square, and laid in the same manner as tig. l; and p i y Figure 6 is a side view of blocks, with a lower or foundation range receiving the surface bloclr's.

Similar marks of reference denote the same parts. 4

In the usual mode of laying paving blocks, each one is independent of the other; and where no foundation is prepared, except gravel, the blocks are often driven down into the softer spots of the bedvhy loads passing over them; they are also loosened by the action of the horses feet pulling in one direction, whilel the wheels, as they follow, produce a concussion in the other direction.

The nature of my said invention consists in a roadway formed of blocks laid at an inclination, so that one block rests partially upon the side of the next, as well as upon the sand or other foundation. By this arrangement the weight that may rest upon one block is taken partially by two or more of the contiguous blocks, and there is no opportunity for the block to work loose in its bed, because in sof doing several contiguous blocks would have to be moved, oneblock lying upon and against. the others. i

In the drawing, a represents the bed of sand or other foundation for the pavement.` b b and c are rangesV of blocks lying at an inclination longitudinally of the-roadway. The blocks b b are laid se that their joints come opposite to the central portions of the blocks c c, so as to ,break joints. V'Ihese blocks b l1 and c c may be thin, as seen in iig. 5, or may be thicker, as seen in iig. 3, or they may be dressed of a diamond shape, the blocks being laid together as in fig. 4. The lo'wer ends of the blocks may be inverted after the upper'surfaees of the blocks are wornvout; or, if desired, this character of block may be laid on foundation blocks d d, set at the opposite inclination, as seen Ain iig. 6. Y

What Iclaim,*and desire to secure by Letters Patent, is-V A i A pavement formed of blocks laid at an inclination, so that one block lies partially upon the side ofthe next., substantially as set forth.

In witness whereof Ihave hereunto set my signature this twelfth day of 'Mai-eh, A. D. 1867.
